8051/8032 Assembler course (7):

SERIAL INTERFACE PROGRAMMING

Perhaps unwittingly, you have been using
the serial communication features of the
8051 or 8032, and the supporting routines
contained in the system monitor,
EMON51, ever since the 80C32 singleboard
computer (our 'course hardware')
wrote its first 'welcome' message on your
terminal. In this course instalment we will
explore the not-so-simple operation of the
serial interface with an aim to grasp the
way it is programmed.
